@Rick-Anderson I will work on it, ok?

@Rick-Anderson Should I add the sample code in this repo or AspNetCore.Docs.Samples?

Either place. If we expect many customers to download the code, we prefer the samples repo.

@Rick-Anderson the current sample for this page are here: https://github.com/dotnet/AspNetCore.Docs/tree/main/aspnetcore/web-api/action-return-types/samples. Do you want, for .NET 7, we have them in the new repo as well?

No, let's keep it here. We don't want to duplicate it for sure. cc @tdykstra
